Overview/UF
Ultrafiltration membranes are capable of separating larger materials such as colloids, particulates, fats, bacteria, and proteins, while allowing sugars, and other low molecular weight molecules to pass through the membrane.
With a pore size range between 1KD to 300KD, ultrafiltration membrane pore sizes fall between that of nanofiltration and microfiltration. UF membranes typically operate between 50–120 PSI (3.4–8.3 bar) and are dependent on transmembrane pressure to drive the separation process. Other polymeric ultrafiltration membrane characteristics include robust chemical and temperature resistance, and low fouling tendencies if proper pretreatment is employed.

4: Applications
Nanofiltration membranes are a relatively recent development, and offer greater selectivity of ions vs. reverse osmosis membranes that reject all ion species in a feed stream. This unique characteristic provides flexibility in separation process development that can greatly impact performance and profitability, especially for industrial applications. Here are some common applications:
Dairy,food and beverage ------
Lactose and whey demineralization in dairy processing
Lactose and whey concentration
Protein concentration
Industrial/Wastewater Treatment ------
Removal of natural organic matter in water and wastewater treatment Reduction of hardness in water purification
Sulfate removal from seawater and chemical processes Desalting of process streams in various industries
